摘要:
Embodiments of the present disclosure are directed to carbon-containing composites which are suitable for use as electrodes in electrochemical systems. The composites are formed from a scaffold of graphene and carbon nanotubes. Graphene flakes form a plurality of generally planar sheets (e.g., extending in an x-y plane) separated in the direction of a composite axis (e.g., along a z-axis) and approximately parallel to one another. The carbon nanotubes extend between the graphene sheets and at least a portion of the carbon nanotubes are aligned in approximately the same direction, at a defined angle with respect to the composite axis. At least a portion of the scaffold is embedded within a porous carbon matrix (e.g., an activated carbon, a polymer derived graphitic carbon, etc.).
